Q:What does "1210" mean in patch LED?

At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.

Q:How can I install the patch LED lamp belt on the wood chip casting board? With double-sided glue will be hot, and can not use the clip on the screw, what should I do?

Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.

Q:How many volts is a single LED on the LED patch band?

LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.

Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?

The ten patch LED lamps are connected in parallel with rated power of 5 watts and voltage 3.3V.

Q:Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?

The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim

Q:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!

If the power of the lamp, because heat high power do very well, so not good welding, the temperature at the highest (300 degrees), the use of horseshoe iron head, not waiting to solder, because the heat is very powerful, quick action.

Q:What should I notice when I want to solder 1206 LED patch type luminous tube on fine copper wire?,

I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.

Q:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?

SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.

Q:What is patch SMD-LED?

This really do not know how to answer you, like a sheet of the same type of solder paste used to operate, it can be said that the plug-in is not, it is patch it!

Q:What are the storage requirements of SMT patch LED (LED)?

Clean? use no designated chemical liquids to clean SMD LED. These chemicals may damage SMD LED.. When necessary, wipe LED at room temperature with alcohol and dry at room temperature for 15 minutes before use? the effect of ultrasonic cleaning on SMD LED is related to the ultrasonic power and the SMD LED assembly method, and shall be checked in advance to ensure that the ultrasonic cleaning process does not impair the SMD LED
